Pathophysiology Final Exam
1. A nurse caring for a patient with a diagnosis of lung cancer is aware that the primary risk factor for developing lung cancer is:
- A. Alcohol consumption
- B. Smoking
- C. Poor diet
- D. Environmental exposure
Correct answer: B
Rationale: The correct answer is B: Smoking. Smoking is the primary risk factor for developing lung cancer. Tobacco smoke contains numerous carcinogens that can damage the cells in the lungs, leading to the development of cancer. Alcohol consumption (Choice A), poor diet (Choice C), and environmental exposure (Choice D) can contribute to overall health risks, but they are not the primary risk factors specifically associated with the development of lung cancer.
2. The nurse is administering a beta blocker to a client with a heart rate of 58 bpm. What is the nurse’s priority action?
- A. Administer the beta blocker as ordered.
- B. Hold the beta blocker and notify the healthcare provider.
- C. Increase the dose of the beta blocker.
- D. Monitor the client’s heart rate and reassess in 30 minutes.
Correct answer: B
Rationale: The correct answer is B. A heart rate of 58 bpm is considered low, and beta blockers can further decrease the heart rate. Therefore, the nurse's priority action should be to hold the beta blocker and notify the healthcare provider for further assessment. Choice A is incorrect because administering the beta blocker without considering the low heart rate can worsen the condition. Choice C is incorrect as increasing the dose of the beta blocker can lead to further slowing of the heart rate, which is not safe in this situation. Choice D is not the priority action; holding the medication and seeking guidance from the healthcare provider is more crucial.
3. Which therapeutic approach is most effective for managing obsessive-compulsive disorder (OCD)?
- A. Cognitive-behavioral therapy
- B. Psychoanalysis
- C. Medication management
- D. Group therapy
Correct answer: A
Rationale: Cognitive-behavioral therapy (CBT), especially exposure and response prevention, is considered the most effective therapeutic approach for managing obsessive-compulsive disorder (OCD). CBT helps individuals identify and modify their distorted beliefs and behaviors related to OCD, while exposure and response prevention specifically target the core symptoms of OCD by gradually exposing the individual to feared stimuli and preventing compulsive responses. While medication management can be used as an adjunct to therapy, CBT has shown to have long-lasting benefits in reducing OCD symptoms and improving the overall quality of life. Psychoanalysis focuses more on exploring unconscious conflicts and childhood experiences, which may not be as effective for OCD. Group therapy can be beneficial as a supplemental treatment but is not typically as effective as individual CBT tailored to the specific needs of the individual with OCD.
4. While reviewing the monitor tracing of a client in labor, a nurse notes late decelerations. Which of the following interventions should the nurse perform?
- A. Administer oxygen via nasal cannula
- B. Reposition the client onto her left side
- C. Administer an amnioinfusion
- D. Provide reassurance to the client
Correct answer: B
Rationale: Repositioning the client onto her left side is the appropriate intervention when late decelerations are noted on the monitor tracing. This action helps increase uteroplacental blood flow by relieving pressure on the vena cava and aorta, improving fetal oxygenation. Administering oxygen via nasal cannula may be indicated for variable decelerations, not late decelerations. Administering an amnioinfusion is not the primary intervention for late decelerations. Providing reassurance to the client is important but addressing the underlying cause of late decelerations takes precedence.
5. What is the primary action of bisphosphonates when prescribed to a patient with osteoporosis?
- A. It inhibits bone resorption, which helps maintain bone density.
- B. It stimulates new bone formation by increasing osteoblast activity.
- C. It increases calcium absorption in the intestines, which helps build stronger bones.
- D. It decreases calcium excretion by the kidneys, helping to maintain bone density.
Correct answer: A
Rationale: The correct answer is A: "It inhibits bone resorption, which helps maintain bone density." Bisphosphonates work by inhibiting bone resorption carried out by osteoclasts, thereby preventing the breakdown of bones and helping to maintain or increase bone density in patients with osteoporosis. Choices B, C, and D are incorrect because bisphosphonates do not directly stimulate new bone formation, increase calcium absorption in the intestines, or decrease calcium excretion by the kidneys.
